ST/UPC Singlemode Fibre Optic Cable 3m - 9/125 Duplex, LSZH Patch Lead

Get a reliable, verified singlemode fibre patch lead built for ultra-low reflectance connections. This duplex ST/UPC fibre optic cable pairs two ST/UPC connectors over a 9/125 micron singlemode core, giving you a tested, first-quality patch lead for structured cabling and telecoms installations.

Every cable is verified 100% before it leaves the factory, so you can trust the connection quality out of the box. The LSZH (Low Smoke Zero Halogen) outer sheath is designed for installations where cable safety matters, such as commercial buildings, data rooms and public spaces, releasing less toxic smoke in the event of fire compared to standard PVC jacketing.

Good to know

UPC connectors are polished flat, giving a different reflectance profile to APC connectors, so always match connector type at both ends of a link and against your equipment's specification. Confirm your transceivers and patch panels are rated for ST/UPC singlemode fibre before installing, and avoid tight bends when routing the cable to protect signal quality.
